Roofing
Shingles, flashing, gutters, ventilation, ice dams. What's safely DIY (gutter cleaning, minor patches) versus what's fall-risk pro-hire (multi-story, steep pitch, full replacement).
Overview
Residential roofing is one of the highest-risk DIY categories in the home. Every year in the US, thousands of homeowners are injured in falls from residential roofs — many while doing 'simple' tasks like gutter cleaning. Our editorial approach: we bias hard toward calling a pro for anything above single-story, low-pitch, dry-conditions work.
Roofing systems include shingles or membrane (the visible surface), underlayment (waterproof layer beneath), flashing (metal at penetrations and edges), ventilation (soffit, ridge, gable vents), and gutters. Failures usually appear as leaks — but the water may travel far from the actual leak point before appearing inside.

Shingles & roofing material
Types, aging signs, small repairs. Full replacement is always pro-hire.
Flashing & sealing
Metal flashing at penetrations, chimneys, valleys. Leaks usually start here.
Gutters & drainage
Cleaning, repairs, downspout extensions. Ground-based gutter tools reduce ladder risk.
Attic ventilation
Balanced intake and exhaust. Prevents ice dams, extends shingle life, reduces cooling costs.
Ice dams & winter roofing
Prevention, roof rake use, emergency response.

DIY vs pro — the honest framework
Safe for DIY (single-story, dry conditions, proper fall protection):
- Ground-based gutter cleaning with extension tools
- Roof rake use (from ground, in winter)
- Attic ventilation inspection
- Attic insulation top-up
Fall-risk — hire a pro:
- Any roof work on multi-story homes
- Steep pitch (6:12 or greater)
- Wet, icy, or windy conditions
- Full shingle replacement (a professional job by any standard)
- Chimney work
Frequently asked questions
For single-story homes with low pitch and dry conditions: yes, with proper fall protection (harness, rope, anchor). For anything above single-story or with any pitch above 4:12, we recommend hiring. The insurance implications of a homeowner falling from their own roof are also significant — many homeowner policies exclude DIY roof work.
20–30 years for standard 3-tab shingles, 25–50 years for architectural shingles depending on climate and quality. Signs of end-of-life: shingle granule loss (bare spots), curling edges, missing shingles, moss/algae growth. See shingle lifecycle guide.
Get 3 quotes. Check that each contractor: is state-licensed and insured, provides written estimates, has been in business at least 5 years, and offers a written workmanship warranty. Avoid door-to-door 'storm chaser' contractors who appear after severe weather.
It depends on your tree cover. Heavy leaf exposure: yes, they significantly reduce cleaning frequency. Minimal tree cover: probably not — the cost isn't worth the small maintenance savings. See gutter guards analysis.
